Fit, Compatibility, and Installation Tips

Designed for trailers with a 5-lug 4.5-inch bolt pattern and a 3500 lb axle rating, this kit fits 1-1/16 to 1-3/8 inch spindles. To confirm compatibility, measure the old hub size and verify that the bearings are L44649 and L68149. If measurements aren’t clear, refer to the accompanying illustration for bolt pattern guidance and the note on measurement A and D to determine 5x4.5".

Durability and Quality

Every component is crafted with attention to long-term durability. The hub body uses carbon steel with an anti-rust treatment, while the bearing assemblies are selected for precision and low operating noise. The seal design helps prevent leakage, supporting robust on-road performance across trips and seasons.
